Claims.

This invention relates to a frame for placing around type matter while it is being proved. In order that a proof may be printed by a modern proving press which will show the faults of 5 pieces of type as well as typographical errors, the feet of the type should rest squarely on the true surface of the press bed. It has long been the practice to take a proof from the type while in the galley, the type being held in place by pieces of wood and wedges. The bottom of a galley is usually thin sheet metal of varying thickness often somewhat dented and warped from use and although placed on an accurate machine press bed it not only precludes the possibility of the type face being type high from the bed but does not even permit the type height to be uniform.

In removing type from a galley in which it has been composed and sliding it on to the bed of the press it should be locked in a chase or framesuch as is used on printing presses and in which it is held squarely on its feet. These frames are generally rigid in construction and large enough to encompass the largest form of type make-up that the press will print. When smaller forms. are used the unused space is filled with blocking and wedges.

When using a chase or frame in a proving press it is highly desirable that it be adjustable in both width and length and that it be provided with locking devices so that the sides and ends of the chase compress the type and hold it firmly in the position for which it was composed. In order to meet the large range of sizes of column and page, met with in a printing office,

it is desirable to use a minimum of sizes and frames and consequently the adjustable range of the frame should be as great as possible.

It is also desirable that the type be placed in the frame before it is removed from the galley and this may be accomplished by placing the frame with one end open in a galley on a type casting machine so that when the composed type is placed on the galley it is placed between the .side bars of the frame, the sides having previously been adjusted to the column measure or length of the line of type as set. When the desired amount'of type has been set the fourth side of the frame is locked in place and the form can be slipped off the galley on to the press bed.

A frame to accomplish the above results is shown in the accompanying drawing forming a part hereof and in which Figure 1 is a plan view of the frame shown securely holding composed type.

Figure 2 is a side elevation thereof. Figure 3 is an end elevation thereof from the ft.

Figure 4 is an end elevation thereof from the right. 6

Figure 5 is a side elevation of the clamp.

The frame consists of two side bars I of angle steel of a length of approximately that of the bottom of the galley. One end of these bars in their vertical portions. is notched as at 2. In 10 these notches is placed a bolt 3 which may be readily removed through the notch and which is to be tightened up to hold the type securely. A piece of reglet or type metal 4 of a length equal to the column measure is placed adjacent the 15 bolt and separates the side bars the requisite amount and after its placing the nut should be screwed up finger tight against the measure. The locking bar or clamp 5 consistsv of a similar piece of angle steel with deep right angular 20 notches 6 cut in one wall of the bar. These notches are intended to be placed downwardly over the side bars, and wedges I and 8 are then forced between the outer sides of the side bars and the inner side of the notches. When the 25 desired amount of the composed type 9 has been placed between the side bars and against the type metal the clamp 5 is placed over the side bars and the wedges forced into firm holding position. The composed'type may be lifted and so moved around at will, held tightly in the frame.

Forcing home the wedges moves the clamp 5 longitudinally forcing the type firmly against the type metal 4 and simultaneously forcing the side bars together in firm clamping position so that 35 when the wedges are firmly in place the type is held securely both longitudinally and laterally, there being a balancing of forces at right angles to each other by the action of the wedges.

' Bolts of various lengths could be used and the 40 notches 6 in bar 5 also allow for considerable variation in type line length when using wedges of different thicknesses. The clamp 5 may also have additional notches as shown at Ill so that the same clamp may be used for considerably 45 longer lines of type.

The type locked in this frame is placed on the bed of the proving press in a position identical to that which it will assume on the printing press and consequently an accurate proof of all the faults in the type may be obtained.

While there has been illustrated and described the preferred form of construction of the invention this construction is capable of variation 5 and modification without departing from the spirit of the invention.

What is claimed as new and desired to be secured by Letters Patent is:

1. A type holding frame comprising a pair of longitudinal bars, a variable width connection therefor at one end, a clamp extending thereover at the other end, and means to force said clamp longitudinally into type holding positionagainst the variable width connection.

2. A type holding frame comprising a pair of longitudinal bars, a variable width connection therefor at one end, a clamp extending thereover at the other end, and means coasting with said and simultaneously to force said clamp longitudinally to force type against the variable width connection, to grip the type simultaneously in' two directions.

4. A type holding frame comprising a pair of V '5. A type holding frame comprising a pair of longitudinal bar s,,a connection therefor'at one end, a clamp extending thereover at-the other end and a wedge between the bar and the'clamp to be driven lengthwise of the bars toward the type to simultaneously grip thetype in two di-' 7 rections.
